By summarizing a large number of clinical cases and treatment experience, we feel that minimally invasive laparoscopic treatment of cryptorchidism has the following main advantages: 1. minimally invasive, the pain of the child is greatly reduced; 2. the testicle can be descended to the maximum; 3. the self-growth of the testicle will be better after the operation; 4. the testicle that cannot be touched before the operation can be well explored.
